How do forces acting on a body affect its stability?
A boy throws a stone straight upward with an initial velocity of 5 m/s from the surface of the Earth. What is the maximum height above the starting point will the stone reach before it starts falling back?
A boy throws a stone straight upward with an initial velocity of 5 m/s from the surface of the Earth. What is the maximum height above the starting point will the stone reach before it starts falling back?
If a dropped object falls 19.6 m in 2.0 s, how far will it fall in 4.0s?
A supersonic bomber which had a momentum of 8,800,000 kg-m/s east, comes to a halt on the ground. What impulse is applied?
A BMCC student is doing an experiment using a string with two fixed ends. If the string length L is 1.0 m, what is the longest possible wavelength of the standing wave on this string in m?
You place a floating buoy on an ocean surface. The buoy stays at the same location but is free to move vertically with the ocean surface. An ocean wave of speed 4.2 m/s and a wavelength of 5.6 m. How many times per second does the buoy oscillate ups and downs? The answer is a number and may not be an integer value.
An organ pipe is closed at one end and open at the other end. It is 0.8 m long. When a standing wave of the longest possible wavelength is formed, what is the frequency of the standing wave in Hz if the speed of sound is 340 m/s? (Hint: First find the longest possible wave length and then calculate its frequency).
A string of a music instrument has a length of 0.64 m. Its mass is 8.6 g. Find the speed of a wave on this string in m/s if the tension on the string is 75.6 N? (Hint: You need to calculate the linear mass density – mass/length in m/kg).
The guitarist from a famous rock band is tuning two guitars. One of them has been tuned and one of the strings is tuned to produce sound wave of frequency 352 Hz. A string on the other guitar produces 7 beats per second when the two strings are played together. What is the highest possible frequency that the second string produces in Hz
